Answer:

  y = -x +3

  m = -1

  b = 3

Step-by-step explanation:

To solve the given equation for y, divide by the coefficient of y.

  (-3y)/(-3) = (3x -9)/(-3)

  y = -x +3

__

The slope is the x-coefficient, M = -1.

__

The y-intercept is the added constant, B = 3.

__

Both equations are graphed in the attachment. Texture has been added to the original so you can see the graphs are the same line.

Suppose 223 subjects are treated with a drug that is used to treat pain and 50 of them developed nausea. Use a 0.01 significance
Colt1911 [192]

Answer: We reject the null hypothesis.

Step-by-step explanation:

Since we have given that

n = 223

Number of subjects developed nausea = 50

\hat{p}=\dfrac{50}{238}=0.21

We need to claim that more than 20% of users develop nausea.

So, Hypothesis:

H_0:p\leq 0.20\\\\H_a:p

test statistics would be

z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}\\\\z=\dfrac{0.21-0.20}{\sqrt{\dfrac{0.2\times 0.8}{223}}}\\\\z=\dfrac{0.01}{0.0268}\\\\z=0.373

At 0.10 level of significance, z = 1.28

Since 0.373<1.28 so, test statistic is less than critical value.

Hence, we reject the null hypothesis.
